To .aN/whom it may concern:

I a fnltizenv ofthe United States, residingat a s eciiication.

Faducah, in thejc'ounty of McCracken'and `State of Kentucky, have invented anew and useful Cushionfiire,l of Which theI following is he invention relatesto improvements in cushion-tires.

i The object oiy the present invention is avoid the use of unreliable pneumatictires and to enable the 'saine tobe readily-made reliable springmetal hoop or `cushion-tire deu sinned` for use on various kinds of Wheels and applied." z Y A furtherobject of the-invention is to prof vide av Wheel ot this character'having adjust-1 able means-for varying the tension of the f parts to increase.

the stiffness vof. .vth e Wheel when desired. f v y"Withv these 'and other objects'in view` 'the inventionconsists inl the)construction` and the claims Vhereto appended,v it being-underpor'tion, size, and niinordetails ol construction within the scope oi the clairns may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention. j

The side portions clearly Ashown in Fig. 2.A lThe outer hoop or noiseless either the outer or inner,f orboth,of the spring-.metal hoops 8 and 9 may be cov- IOS rtube is also provided at opposite sides with '11, which in practice are desi ne to be sufiio TIO . .O with a transverse hoopV or ring 5, 'which is arranged on' *the telly or 'riin4 andWliich-extendslaterally therefrom.' The inner edges f ofthe sides 2 are provided angle rings or'bands 6, which are L-shaped in cross-sec-r 75 j Instead of employing a single ring or band 11 at each side of lthe 'flexible tube or casing two or more of suchrings or bands may be used when additional strength is desired, and as this is obvious illust-ration thereof is deemed unnecessary. These resilient rin s or bands 1 1 4are connected by transverse a( justing devices adapted to compress the said ilexible casing ortube to place the desired tension on the circular springs or hoops 8 and 9. These transverse adjusting devices, which are arranged at short intervals, each comprise a bolt 12 and an interiorly-threaded' tubular member 13, which receives and is engaged by the threaded portieri of lthe bolt. The bolt pierces one oii the walls of the flexible casing and the'interinediate ring or band 11 thereof and the tubular member pierces the opposite wal-lof the flexible tube or casing and the other rin-g or band 11. Each of the sections or nremb-ers oli the transverse fastening device is also preferably provided with a clip-plate 144 for embracing the intermediate rings or bands, asiclearly shown in Figs. 2 and 3 of the drawings. These clip plates ormoni-bers 1st may be omitted, if desired. The exteriorlyarranged rings or bands 11 enable the sides of' the flexible tube or casing to be uniformi` compressed', and by com )ressing the flexible tubeI or easing the circular strings or inet-al hoops 8 and 9 are placed un( er tension, and the desired stiffness is imparted to the tire. Although' in Figs. 1 and 2 of the drawingsthe cushionstire is'shown applied to a wheel'liaving wire spokes, yet it will be readily understood that the tire' isapplicable to all kinds of wheels;

In Fig. 5 of the drawings is illustrated a tire having a flexible tube' or casing 15, provided with an inner wall composed of opposite portions connected by lacing, as clearl shown'at 16. The laced edges oi the flexible casing or I.tube are interposed between the folly 17 and a hoop or band 18, and the casing or` tube 15 is r'ovided at its tread portion with inner an outer resilient hoops or circular springs 19 and 20, which are connected by rivets' 21, piercing the hoops or circular sprin s 19 and 20 and the tread portion of the iiexib el easing l5. The sides of the flexiblev tube or casing are connected by transverselydisposed adjustin devices 22, constructed similar to those be ore described and provided with clip-plates 23,in which are arranged resilient intermediate rings, bands, or hoops'24'. These rings or hoops 24, which are arranged in pairs, are' preferably inthe form of narrow thin bands or heavy wires; but they may be of any referred conii tration and may be-increased or diniinislgie'i in number, accordin to lthe stiilne'ss desired to support the tire and cushion the load.

Iii-Fig. 6 of the drawings is illustrated another form of 'the invention in which a ilexible tube or casing 25 is employed, the tube or casing 25 being an ordinary pni'wuniatiw tire tube or casingoi the clcnchcr typo converted into a spring-hoop cushion-tire. 'l`his tube or casing is provided with intcriorly-arrangedE resilient metal inner and outer circu lar springs or hoops 2G and 27, and the sides oil the tube or casing are connected hy trans versely-disposed adjusting devices 2S, which pierce the side walls, and also intermediate extcriorly-arranged resilient rings or bands 29. The inner portion of the sides oiE the tube or casing are enlarged at 3() and extend- 'ed laterally to engage a rini .'51 having curved In Fig. 7 of the drawings is illustrated' another forni oi the invention in which a flexible tube or casing substantially rcctanguiar in cross-section is employed. The tube or casing is laced at the tread at 33 and providedwith interiorlyarranged resilient inner and outer circular metal rings or hoops 34 and 42, which support the tube or casing and binds it to the iclly or wheel-base. 'lhc sides of the tube or casing are connected by transverse fastening devices 35 and are provided with exterior intermediate resilient bands orrings o6, which are in the form of light rodsor heavy wires. The flexible tube or casing is seated on a niet allic hoop or band 37, which extends laterally beyond the rim or felly portion 3S of the wheel and which also is engaged by elongated clip-plates 39. These clip plates or. clainpin members, which are secured to the sides oY the casing by the transverse fastening devices 35, havo their ends ben-t inwardly at right.- angles to form inner and outer lugs or flanges 4() and 41. The inner lugs or flanges 40 engage and interlock the flexible' casing or tube with the inner hoop or band 37 and the outer lugs or flanges 41' engage the iiiterinediatc resilient hoops or bands 36.` It will be readily seen 'that this form of the invention provides a light, noiseless, hi lily-resilient cushion-tire the stiffness of wiich can be readily and easily increased by the addition of one or more circula-r springs or hoops placed on the interior of the tube or casing within the space between the hoops 34- aud 42 or by the addition of one or more pairs of' resilient hoops or rings 36, arranged within the clip-plates 39 on the outside of the tube or casing between the flanges or lugs 4() and 41.

It will be seen that the improvements lOO x sired strength and resiliency.

herein shown and d'escribedare applicable toa large variety of styles of'tires andlthat either or all of the outer orfinner circular 'hoops'or rings may vary in size, coniigura-v tion, and number to secure a tire 'of the d e- Also it 'will beclearly seen that the circular springs or hoops"- are adaptedgto afford'v resiliency or cushion# .ing effectto an ordinary pneumatictire and that they will render the same puncture- 1 proof and may be secured to themby any suitable means.. l j l Having thus fully described my invention,
